We have just posted an interview with Zachary Timmerman, Project Manager of College Hoops 2K6. These questions are specific to the upcoming Xbox 360 version. Sorry, they didn't answer the release date question.

Operation Sports: "Will the potential bug be fixed? (Player changing to an A potential if edited) or can we change potential for a player?"

Zachary Timmerman: "You are now able to change the potential of a player just as you are with other ratings. Editing a player will no longer change his potential unless you choose to do so."
